This is why I love AK OOP

My image is T/LAG - playing a decent amount of hands with LOTS of raising. Maybe my opponent picked up on this on the turn and tried to make a move?
Villian is 30/3 after 130 hands, fairly weak-tight to say the least. Haven’t watched any of his hands in particular, but with stats like those, I think he should be respected.

my thinking:
on turn, I didn't see it to be a big deal to give a free card. Maybe I should have bet. Backdoor FD !AND! broadway draw. ...and also to control the size of pot. sigh i HATE being OOP with TPTK

river - perfect card for a c/c but the fact that he went ALL IN just scurred me away - I was getting about 2/1 odds here but I honestly put him on a set of 2ces. then again, 22 or 10 10 or broadway are the ONLY possible holdings he could have that beat me - I was pondering the decision but eventually the timer ran out...sigh

What do ya'll think?
